4 Claims. (Cl. 221-61) My invention relates in general to receptacles of metal, having a bottom cross-Wall 5 and a. fullfor dispensing powder which by reason of its naopen top 6 with an 'outer flange I. ture and use requires a modicum of the receptacle The bottom wall 5 is apertured, being provided Ii'content. with one or more openings of relatively small size,

The or more relatively small or contracted apertures. outer diameter of the sleeve is substantially the Such receptacles, for example, are hand shakers same as the inner dameter of the bottle neck and 10 for various powders, salt, pepper, talcum, tooth the length ofthe sleeve is proportioned to that of 10 powder, insect powder, and many other fluent the neck-throat, so that when said sleeve is solids. slipped down into the neck to a frictionally tight Though my invention is not essentially confined fit with its flange l resting upon the top of the r.- to'glass containers, still, for several reasons which neck and limiting its insertion, said sleeve by I shall hereinafter set forth, it is structurally reason of its apertured bottom wall 5, presents in 15 adapted for glass bottles, in which connection it the bottle-throat a diaphragm control well down is my present opinion that its best use lies. within the neck, and restricting by its opening 8, The object of my invention is to provide for the flow of the powder to the proper modicum such containers, particularly glass bottles, without when the bottle is tipped.

55 a i i z gj g g g g j g i i' following should be noted. Reducing stoppers in 45 522 3 g W w e p c 0 1 S the form of apertured corks are usually resorted to for the sake of frictional security.

Referring first to Fig. 2, 4 is a sleeve, preferably Another difl'iculty which from experience I 55 have found outstanding in using metal sleeves as dispensing controllers in glass bottles, arises from the fact that glass and metal have different coeflicients of temperature expansion and contraction, which difference tends to, and often does, result in breaking the bottle neck. This is true no matter how mathematically perfect the cylindrical character of the bottle throat, and the metal sleeve may be; but in addition, and perhaps most important, I have found that in manuiacturing practice, the throats of glass bottles are seldom true circles in cross section, but depart therefrom to some extent, so that the metal sleeve, if truly cylindrical, fails to find a tight frictional fit. But the split sleeve, on account of circumferential resilience, not only guards against bottle breakage due to differences of expansion and contraction, but also accommodates itself to any irregularity in the bottle throat, and thus can be made frictionally tight and yet easily removable.

I claim:-

1. A powder-dispenser comprising in combination a glass-bottle having a neck with an open throat; a metal split sleeve seated in said throat in frictional contact throughout its length with the throat wall, said sleeve having a penetrationlimiting flange resting on top of the neck, one end of said sleeve being open and the other end having an apertured, cross Wall of less discharge capacity than the open end; and a cap fitted upon and covering the neck of the bottle.

2. A powder-dispenser comprising in combination a glass-bottle having a neck with an open 1 throat; a metal split-sleeve seated in said throat in frictional contact throughout its length with the throat wall, said sleeve having a penetration-limiting flanges resting on top of the neck, the upper end of said sleeve being open, and the lower end having an apertured relatively stiff cross wall of less discharge capacity than the upper end; and a cap fitted upon and covering the neck of the bottle.

3. A powder-dispenser comprising in combination a glass-bottle having a neck with an open throat; a metal split-sleeve seated in said. throat in frictional contact throughout its length with the throat wall, said sleeve having a penerationlimiting flange resting on top of the neck, the lower end of said sleeve being open, and the upper end having an apertured relatively stifi cross wall of less discharge capacity than the lower end; and a cap fitted upon and covering the neck of the bottle.

4. A powder-dispenser comprising in combination a glass-bottle having an externally-threaded neck with a full-open throat; a metal sleeve in said throat of a length proportioned to that of the neck-throat and of a diameter adapting it for readily insertable and removable frictional contact throughout its length with the throat wall, said sleeve having a penetration-limiting flange resting on the top of the neck and a fullopen lower end, and having also a partially open, relatively stiff cross wall at its upper end, of less discharge capacity than the full-open lower' end; and a flat-top screw-cap fitted upon the neck of the bottle to lie closely upon and cover the parti ally open upper end of the sleeve.
